Description

TORQUE LIMITING FILTER WRENCH
Background of the Invention The present invention relates to hand tools, particular wrenches, and most particular to oil filter wrenches configured and adapted for the removal and installation of cartridge and/or canister oil filters (hereinafter referred to as "oil filter").
Oil filters are generally screwed on to an engine, during the installation process a sufficient amount of torque is required for the oil filter to seal properly while an excessive amount of torque will make the oil filter difficult to remove or cause damage to the interfacing surfaces.
Mechanics generally utilize a torque wrench in conjunction with an oil filter wrench or hand tighten the oil filter, the former requires multiple tools to perform the task and the latter results in a possible under or over torque condition.
It is therefore an object of the present invention to provide an oil filter wrench that is used to remove and install oil filter to the correct torque.
Summary of the Invention The present invention provides a filter wrench that will click and cease to apply torque when pre-set torque is reached.
The present invention comprises a socket member housing of the cup like shape 10 for axially receiving a portion of an oil filter 11, the closed end of the housing is configured to form a nut 12 that house a torque limiting clutch mechanism.
The clutch mechanism is comprised of an end cam 13 that has axial force applied by either a spring or Belleville washers 14 (hereinafter referred to as "spring") forcing it against cam follower 18; quantity of force and thus torque limit is adjusted by the depth that the threaded disc member 15 is thread into the housing and/or the spring rate of the spring 14.
In operation a standard drive socket with extension 16 is inserted into the square hole of the end cam at location 17 to apply torque.
Brief Description of the Drawings Fig. 1 is a perspective view of the present invention connected to a standard drive socket with extension and engaged over an oil filter.
Fig. 2 is a bottom view of the present invention connected to a standard drive socket with extension.
Fig. 3 is across-section view along the line A¨A of Fig. 2 of the present invention connected to a standard drive socket with extension and engaged over an oil filter.
Fig. 4 is a detail view of circle B of Fig. 3 of the clutch mechanism of the present invention.
